This question already has an answer here:
Yesterday my computer stayed open all night and then when battery was empty it turned off. Its normal for my computer. But when at morning I turned it on, there wasn't login screen. It crashed everytime. After reinstalling Xorg, lightdm, ubuntu-desktop and doing some other things login screen appeared. But after login I can see only my desktop and System crashed warnings that appears in ubuntu from times when unity came. In guest mode everything works well. I created new user and assigned him as admin (All privilages) and logged in to his account. Now I'm writing from that user account and everything works very well. So, How I can restore my main account?
Selecting Unity Plugin from ccsm not worked (login to user account, go to tty1 and entering export DISPLAY=:0 and then ccsm + switching to F7). + reinstalled ccsm Half of space in SSD is empty, so its not memory problem. Wallpaper in its place :D
